Variant 12-52014933-T-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_181711.4(TAMALIN):c.922T>G(p.Phe308Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F308L) has been classified as Likely benign.

Genes affected

TAMALIN (HGNC:18707): (trafficking regulator and scaffold protein tamalin) This gene encodes a protein that functions as a molecular scaffold, linking receptors, including group 1 metabotropic glutamate receptors, to neuronal proteins. The encoded protein contains conserved domains, including a leucine zipper sequence, PDZ domain and a C-terminal PDZ-binding motif. Alternately spliced transcript variants have been observed for this gene.[provided by RefSeq, Dec 2012]

The c.922T>G (p.F308V) alteration is located in exon 8 (coding exon 8) of the GRASP gene. This alteration results from a T to G substitution at nucleotide position 922, causing the phenylalanine (F) at amino acid position 308 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
